Title: Telephone stations
IPC: H04M9/08
Filed: 1971-09-07
Abstract: 1334103 Substation equipment SIEMENS AG 7 Sept 1971 [8 Sept 1970] 41573/71 Heading H4K A portable substation incorporates a tone caller and an incoming speech amplifier whose gain is reduced so as to reduce the possibility of singing when the station is placed in its transmit mode by the operation of a transmit/receive switch (speak key). The latter Sp is effective when operated to remove a short circuiting capacitor C1 from the wiper of a potentiometer R1 so that the full track resistance thereof is incorporated in the emitter circuit of transistor amplifier T1. The potentiometer is adjusted for optimum received speech volume in the face of different length lines. The calling signal is of 1200 c.p.s. which is detected by an analyser B1200 that incorporates a threshold and a persistence circuit as well as a speech guard circuit. The latter includes an oscillator and a diode. The analyser closes a transistor switch which supplies power to a square wave low frequency generator G2 whose output chops a high frequency signal supplied by a generator G1 to a loud-speaker L so as to simulate a ringing signal. In order to transmit a calling signal, key R is operative to couple power to generator G1 via diode Gr1, to couple G1's output to line, to place T1 in its low amplification state and to prevent the analyser output from being effective. The station may be tested by operating keys R and P together so that the generated tone is now chopped by G2's output and applied to speaker L thus signifying correct operation of the generators and of the analyser. Power for the station is supplied by local battery U.

Title: Semiconductor Devices having Insulating Film and Method of Treating Same.
Inventor: ONO MINORU
IPC: H01L23/29
Filed: 1967-09-14
Abstract: 1,197,641. Semi-conductor devices; discharge apparatus. HITACHI Ltd. 14 Sept., 1967, No. 41946/67. Headings H1K and H1X. An electric charge is provided permanently on the surface of an insulating film on a semiconductor substrate, thereby controlling the concentration of charge induced within the surface of the substrate by the ions present in the insulating film. The film may, for example, be of SiO 2  on a Si substrate, Si 3 N 4  or Al 2 O 3 , Ge or intermetallic compounds also being referred to as substrate materials. The charge may be applied by means of a corona discharge appartus comprising a central tungsten wire 7, Fig. 16, surrounded by an earthed cylindrical copper electrode 6 having a segment missing, the semiconductor substrate 3 carrying the film 4 being mounting on an earthed conducting plate 5. Charge of either polarity may be applied depending upon the application. The charge has been found to diminish to a certain level as a function of time after the initial charging-up process, and this partial discharge, which is believed to be due to the migration of positive impurity ions within the insulating film, can be speeded up by heating. A second charging process is followed by a very much smaller degree of discharge. The amount of charge on the insulating film may be controlled by means of an ionized atmosphere, produced for example by U.V. light or X-rays, and this method of control may be used to limit the charge to only part of the surface. The application of a layer of an anti-static agent or the inclusion of a phosphorus oxide, e.g. as a phosphosilicate glass, in the insulating film similarly may be used to control the charge. In one application a portion 29, Fig. 9, of the surface of the oxide layer 24 of a N-channel depletion mode MOS field effect transistor is provided with a positive charge to improve the drain current/gate voltage, characteristic. In the case of a P-channel enhancement mode device the charge applied is negative. PNP or NPN Si planar transistors having SiO 2  coatings may have their current gains increased by the application of permanent charges to the surfaces of the oxide coatings. The Specification includes a description of a method of testing the stability of a silicon oxide film on a Si substrate by measuring the capacitance/voltage characteristic of an MOS diode with various charges applied to the oxide surface. The electrode applied to the oxide in this case comprises a copper pipe having mercury applied to the end contacting the oxide.

Title: Improvements relating to Heat Exchange.
IPC: G21C15/02
Filed: 1967-09-14
Abstract: 1,194,249. Cooling discharge tubes. COMPAGNIE FRANCAISE THOMSON-HOUSTON-HOTCHKISS BRANDT. 14 Sept., 1967 [15 Sept., 1966], No. 41950/67. Heading H1D. [Also in Divisions F1 and F4] A heat transfer surface 1 applicable to electron tubes (Figs. 3-5) is formed with throats or grooves 9 extending in a direction 12 at an angle of between 45 and 90 degrees to the general direction 11 of a forced flow of liquid over the surface, each groove having a depth b greater than its width d, and a guide wall 2 being located adjacent the heat transfer surface so that the liquid flow 11 is confined between the surface and the wall. The arrangement is such that heat is transferred between the liquid and the surface by local evaporation accompanied by recondensation of the vapour in the mass of the liquid. In a typical example described the throats or grooves 9 are 2 mm. wide x 7 mm. deep the distance e of the guide wall 2 from the surface being from 0À3 to 3 mm. As shown, evaporation of the liquid takes place at zones 20-22 of progressively increasing temperature in the throat or groove, and the vapour thus formed discharges at high velocity into the main liquid stream 11 where it is condensed by turbulent admixture with the liquid. It is said that this high turbulence also ensures a liquid feed into the grooves 9 sufficient for the needs of vaporization. The wall 1 may be cylindrical in which case the throats may comprise annular, helical, or longitudinal grooves therein on either the convex or concave surface of the cylinder. In cross-section, the base of the throat may be straight, or rounded (Figs. 3-5), or the crosssection may be triangular (Figs. 6/7). Guide vanes (33, 34, Figs. 3/4) may be attached to the wall 1 or to the wall 2 to direct liquid flow in the space 19 between the walls. Two grooved heat transfer walls may be disposed face to face, each serving as a guide wall for the other. Applications particularly described include an electron tube (Figs. 3/4) and an electron beam tube (Fig. 5) in which the wall constitutes the tube anode. Also described in connection with electron tubes are the provision of an elastic hollow body 37 (Fig. 4) in the liquid stream to damp out abrupt variations in pressure which may occur therein.
